Description
Technical field
The utility model belongs to water treatment field, relates to a kind of equipment with the microbiological treatment emulsifiable oil waste water.
Technical background
Oily(waste)waters such as the oil in water emulsion that industries such as oil production, ferrous metallurgy, oil refining, electric power and mechanical workout produce in production technique, petroleum-type oil, tensio-active agent, because of its complicated component, be difficult to handle to qualified discharge, conventional treatment process is to adopt steps such as dosing, breakdown of emulsion, coagulation, precipitation and strong oxidation, the problem that this technology exists is: 1) complex process, labour intensity is big, poor stability; 2) investment cost height; 3) working cost height, and be difficult to qualified discharge; 4) sludge quantity after the dosing is big, has the secondary pollution problem.In recent years; report with this type of waste water of microbiological treatment has appearred again; " experimental study that cold rolling wastewater is handled " (Shanghai environmental science-1997.016 (012)-0017-0019) as the dynamo-electric design and research institute in Shanghai, East China Normal University; adopt dosing precipitation+SBR biochemistry+sand filtration technology, Al is selected in dosing for use

3Coagulating agent, waste water is used the activated sludge process biochemical treatment behind coagulating sedimentation, this deficiency of utilizing the organism waste water treatment process in the active sludge to exist need to be dosing coagulant, sludge quantity is big, have secondary pollution, and the aeration time in the technology is long, needs 8 hours, the scope of application is narrow, and the oleaginousness in the waste water generally will be controlled at below the 50mg/l.
Summary of the invention
The utility model has overcome above-mentioned deficiency, the microorganism that provides a kind of utilization to form through screening, inoculation, purifying from occurring in nature is handled the technology of emulsifiable oil waste water, entire equipment is simple and easy, need not to be equipped with second pond, working cost is low, operation is convenient, sludge quantity is few, non-secondary pollution and the operation of remaining valid, qualified discharge.The utility model is implemented like this: emulsified oily watewater microbiological treatment equipment, comprise and regulate aeration tank, swash plate grease removal tank, biological aerated filter, it is characterized in that regulating aeration tank, swash plate grease removal tank, biological aerated filter and connect successively, described adjusting aeration tank and biological aerated filter are provided with obligate bacterium throwing device.This equipment is being handled the starting stage, in regulating aeration tank and biological aerated filter, add and screen from occurring in nature, inoculation, the associating flora that purifying forms, the associating flora is made up of gemma Pseudomonas and utmost point Bacillaceae, its activity is greater than 1014/gram, it is powdery or the tubular solids that has carrier, carrier is by anti-tensio-active agent, cereal material, composition such as nutrient substance and buffer reagent, anti-tensio-active agent in the carrier can play dissemination to the complicated pollutent in the oily(waste)water, cereal material, nutrient substance and buffer reagent then offer enough nutritive elements of microorganism and growth factor, improve the treatment effect of microorganism.
In the equipment described in the utility model, before regulating the aeration tank, also be provided with preliminary sedimentation tank and PH equalizing tank, preliminary sedimentation tank is used for the oarse-grained impurity of sedimentation water, guarantee the normal operation of post-order process, because of need not to add flocculation agent, this technology just can make water outlet up to standard, so do not establish second pond in the technology, simplified schedule of operation, saved investment and working cost.
In the equipment described in the utility model, the adjusting aeration tank and the biological aerated filter of employing, its body can be structures, also can be equipment.Regulate the built-up type soft-filler of selecting the easy demoulding of easy conjunctiva in the aeration tank, this filler relatively is fit to the microbial growth of this equipment choosing, what the aerating apparatus of adjusting aeration tank was selected for use is the withstand voltage variable orifice aeration flexible pipe of acid-fast alkali-proof or boring aeration pipe or aeration head, can improve the utilization ratio of oxygen; Adopt the multistage ceramics filling of joining of porous of excellent property in the biological aerated filter, be mixed with organized enzyme in the ceramics filling, because of the Pollutant levels in the biological aerated filter reduce, this environment is unfavorable for microbial growth, can promote microorganism growth after in ceramics filling, mixing organized enzyme, improve biomass, guarantee comprehensive treating process efficient.
The utility model is at the water quality characteristics of emulsified oily watewater, selects the associating flora that forms through screening, inoculation, purifying from occurring in nature, the entire equipment simple structure, and the processing efficiency height, the scope of application is extensive, oily degradation rate 〉=98%, COD
CrClearance 〉=95%, BOD
5Clearance 〉=95%, the water after the processing reaches discharging standards fully.
